I agree with almost everything you say but you are taking it to the extreme (14.64) 14.7
14.64 is not being crazy. That is the stoich rating for standard gasoline, but I am sure you knew that already. You can ready about stoich ratings here, but it doesn't matter. I bet there is a magical tune that auto corrects for fuel type and quality with stock 02 sensors.

First you said the MAF will make changes and you don't need to retune. Wrong Wrong Wrong. The car does not learn anything and can not correct anything in Open Loop.

I was talking about the stock tunes to explain to you how the adaptive control works, but I am sure you have a through understanding now.

There is no point in listing all of them because you can do most of them with a handheld tuner anyway.
Yea right. I would like to see you change injector slopes and pulse width, MAF type, adaptive fuel, base fuel, stoich rating, fuel pump voltage tables, MAF transfer function, correct tip detonation, tune out hesitation with a hand held. You can only change a few settings with a hand held. You can manipulate 1,000s with Advantage.

My tune has 67 major tuning categories changes compared to the stock tune. When you get into each individual table there are 100's of changes. Does that sound like tweaking to you?


Example 2 -97 Cobras both with a set of Kooks long tube headers, do you think that both of those car will take a different tune and make a difference.
Hell Yea especially in a supercharged application. Do you realize that the position and location of the MAF effects the A/F? Do you realize that all MAF's are not calibrated exactly the same? Do you realize that injectors have variances in flow rates from car to car?

Do you realize that there is no magical tune that can auto correct for these variances?

Do some research on the MAF Transfer Function and report your findings.

Plugging in a chip or flash tune and not datalogging to check the tune is STUPID!!!!!!!!!
